Equipment system for agricultural ground soil preparation

Abstract

The equipment system consists essentially of the undercarriage 101 having supporting wheels, the rotary device with dovetailing prongs 102, the sowing machine 103 and the land roller or clod breaker apparatus 104. The system components may be used in various combinations or individually.

We claim: 
     
       1. An equipment system for agricultural ground soil preparation, comprising: a vertically adjustable frame unit, having a trestle-type frame part including a bearing frame for coupling the frame unit to a traction vehicle by a lifting rod assembly or a three-point rod assembly and including a supporting frame, the trestle-type frame part being fixedly arranged at an undercarriage with support wheels;   a rotary device with dovetailing prongs, driven by a power take-off shaft, for producing a soil stream, having a bearing frame with receiving parts for coupling the rotary device to the frame unit, wherein the bearing frame of the rotary device is locked without play in all directions with respect to the frame unit;   a sowing machine with vertically adjustable seed delivery pipes adapted to be mounted behind one another in two rows which follow one another in transverse direction, for delivering seeds into the soil stream produced by the rotary device, having a bearing frame adapted for mounting behind the rotary device, and also being adapted for mounting to the bearing frame of the frame unit;   a clod breaker, having a bearing frame which is adapted to be mounted on either the bearing frame of the frame unit, the bearing frame of the rotary device via separate connecting points on the bearing frame of rotary device, or on the bearing frame of the sowing machine, and which can be pivotably adjusted around a transverse axis;   vertically adjustable plow accessories, adapted to be mounted on the undercarriage of the frame unit or in front of the rotary device; and   a mat-type curtain for guiding the soil stream to the ground behind the seed delivery pipes.   
     
     
       2. An equipment system according to claim 1, wherein the clod breaker can be mounted at an intermediate platform-like frame which extends in backward direction from the frame of the rotary device. 
     
     
       3. An equipment system according to claim 1, wherein the clod breaker is adapted to be coupled to the frame of the undercarriage. 
     
     
       4. An equipment system according to claim 1, wherein the wheels of the undercarriage are attached via an axle unit which employs a longitudinal rocker device to pivotably mount the axle unit around a transverse axis, at the frame of the undercarriage, the axle unit being vertically adjustably supported by support means including a spindle unit, which is adapted to be inserted between the axle unit and the frame of the undercarriage away from the transverse axis. 
     
     
       5. An equipment system according to claim 4, wherein the frame of the clod breaker is a longitudinal rocker device adapted to be mounted at connecting parts provided for the axle unit, pivotably around the same transverse axis, at the frame of the undercarriage, and is adapted to be supported by the spindle unit. 
     
     
       6. An equipment system according to claim 1, wherein a pulley is provided at the undercarriage which can be driven by the power take-off shaft for driving the sowing machine, mounted on the undercarriage. 
     
     
       7. An equipment system according to claim 1, wherein a flap is arranged behind the rotary device, the flap being connected to an upper rotor casing and pivotably adjusted around a transverse axis, the flap delimiting, in upward direction, the clearance for the soil thrown backward by the rotor. 
     
     
       8. An equipment system according to claim 7, wherein at the free end of the flap, a flexible mat is arranged, which is a continuation of the flap and which has approximately the same dimensions as the flap. 
     
     
       9. An equipment system according to claim 1, wherein the plow having holding stems, is vertically adjustably arranged in holding devices which surround the stems in a ring shape and which can be laterally opened in such a manner that the stems can be taken out of the holding devices transversely to their axis. 
     
     
       10. An equipment system according to claim 1, wherein the seed delivery pipes are constructed as a telescope, a lower end piece being fixable on or in an upper segment of the respective seed delivery pipe in differently shifted positions. 
     
     
       11. An equipment system according to claim 1, wherein the seed delivery pipes which are adapted to be swivelled in longitudinal direction of the machine are mounted at a transverse bar by means of clip-type holding devices which can be adjusted in a transverse direction and which, by means of stirrups, embrace the transverse bar in a U-shape wherein on the side of the transverse bar, facing away from the center piece of the stirrups, the clamping pieces have slanted surfaces resting on one another such that one clamping piece, when the U-legs are braced against one another, is pressed against the bar. 
     
     
       12. An equipment system according to claim 1, wherein the seed delivery pipes are held behind one another jointly at a frame or at a transverse bar, which is adapted to be adjusted vertically or longitudinally of the machine while swivelling around its axis. 
     
     
       13. An equipment system according to claim 1, wherein a transmission of the rotary device with dovetailing prongs, which can be connected with the power take-off shaft, has an additional power take-off for a pulley for driving a sowing machine which can be mounted on the rotary device with dovetailing prongs.
